Frequently Asked Questions
Q: What equipment does the 00591-57580-81 CR super seal kit fit?
A: The 00591-57580-81 is a CR (cross-reference) super seal kit for hydraulic pump systems in manual pallet jacks. This kit is designed for equipment from Crown, Toyota, Raymond, Yale, and other brands that use compatible pump assemblies. Verify your equipment model number and current seal part number before ordering to ensure proper fit.
Q: What is the difference between the 00591-57579-81 and 00591-57580-81 seal kits?
A: The 00591-57579-81 is a Toyota OEM super seal kit. The 00591-57580-81 is a CR (cross-reference) version that fits similar pump assemblies across multiple brands including Crown, Raymond, and Yale. Both contain oil-resistant NBR, PTFE, and polyurethane rod, piston, and wiper seals. Verify your equipment compatibility before selecting either kit.
Q: What symptoms indicate the seals in a CR super seal kit need replacement?
A: Signs of seal failure include hydraulic fluid leaking from the pump rod or piston area, visible staining on the pump exterior, reduced pump speed or pressure when raising loads, and difficulty maintaining lifted height. If you notice these symptoms, the seal kit should be replaced to restore hydraulic performance and prevent system damage.
Q: Does the 00591-57580-81 work in cold storage environments?
A: The 00591-57580-81 contains standard NBR and PTFE seals. For consistent performance in cold storage below 0 degrees F, verify the seal kit is rated for low-temperature operation. Elastomers harden in cold conditions and may lose sealing effectiveness. Contact us if your equipment operates in deep freeze or cold storage to confirm this kit meets your temperature requirements.
Q: What is the typical lifespan of a CR super seal kit in daily-use equipment?
A: With daily use, a CR super seal kit typically lasts 2-4 years before seals show signs of degradation. Heavy-duty use, exposure to moisture, and temperature extremes reduce lifespan. Inspect seals every 6-12 months if equipment operates outdoors or in wet environments. Replace proactively if seals show visible cracks, hardening, or persistent leaks.
